A more precise HIV integration assay designed to detect small differences finds lower levels of integrated DNA in HAART treated patients.

ABSTRACT: Many studies report the level of total viral DNA in HIV-infected patients, but few studies report the level of integrated DNA. It is important to measure integrated DNA in HIV-infected patients because the information could shed light on the effectiveness of antiretroviral therapy, especially intensified therapy, when viral loads may remain undetectable. In order to develop an integration assay for patient samples, we enhanced the sensitivity of our prior integration assay. To do this, we exploited a technique that we developed, called repetitive sampling, and optimized reaction conditions for rare event detection, rather than large dynamic range. We also designed our primers to match more conserved regions of HIV. The result is a new, sensitive, quantitative assay that allows us to measur
